<h2>理解发布周期<a class="headerlink" href="#id1" title="Permalink to this heading"></a></h2>
<p>从 Nautilus 版（ 14.2.0 ）起，每年是一个新的稳定版发布周期，
定在 3 月份发布。各系列的稳定版都会取个名字（如 Mimic ）、
和一个主版本号（如 Mimic 的是 13 ，因为 M 是字母表的第十三个）。</p>
<p>各版本都是以一种头足纲动物命名（一般是常见名字，
因为拉丁名不好记、也不好拼写）。</p>
<p>版本号包含三部分， <em>x.y.z</em> 。 <em>x</em> 标识发布周期
（如 Mimic 的是 13 ）； <em>y</em> 标识发布类型：</p>
<ul class="simple">
<li><p>x.0.z - 开发版（适合早期测试人员、和胆肥的人）</p></li>
<li><p>x.1.z - 候选发布版（适合测试集群、胆肥的用户）</p></li>
<li><p>x.2.z - 稳定、缺陷修正版（适合普通用户）</p></li>
</ul>
<section id="x-1-z">
<h3>候选发布版（ x.1.z ）<a class="headerlink" href="#x-1-z" title="Permalink to this heading"></a></h3>
<p>在最初计划的稳定版发布前大概两个月，会把功能确定下来，
之后的工作重心将转移到稳定性和缺陷修正上。</p>
<ul class="simple">
<li><p>候选发布版每 1-2 周发布一个</p></li>
<li><p>用于最终测试，以及验证即将到来的稳定版</p></li>
</ul>
</section>
<section id="x-2-z">
<h3>稳定版（ x.2.z ）<a class="headerlink" href="#x-2-z" title="Permalink to this heading"></a></h3>
<p>一旦初始稳定版确定（ x.2.0 ），之后会有不定时的修正版，包含了缺陷修正和（偶尔的）小功能移植。缺陷修正会暂存起来，并包含在下一个小版本中。</p>
<ul class="simple">
<li><p>每 4 到 6 周一个稳定小版本</p></li>
<li><p>用于生产环境部署</p></li>
<li><p>在两个完整的发布周期间持续移植缺陷修正（ 2 年）</p></li>
<li><p>可以从最新的两个稳定版（从 Luminous 起）在线升级、滚动升级，
并通过了测试；</p></li>
<li><p>可以从前一个稳定的小版本在线升级、滚动升级，
并通过了测试；</p></li>
</ul>
<p>对于各稳定版：</p>
<ul class="simple">
<li><p>定期进行<a class="reference external" href="https://github.com/ceph/ceph/tree/master/qa/suites/">集成和升级测试</a>，而且 Ceph 开发者们会分析<a class="reference external" href="http://pulpito.ceph.com/">其结果</a>。</p></li>
<li><p>在开发分支（ <code class="docutils literal notranslate"><span class="pre">master</span></code> ）中已经修正的<a class="reference external" href="http://tracker.ceph.com/projects/ceph/issues?query_id=27">问题</a>也会按计划移植；</p></li>
<li><p>如果稳定版里发现了个问题、并<a class="reference external" href="http://tracker.ceph.com/projects/ceph/issues/new">报告</a>到了上游， Ceph 开发者会分类处理。</p></li>
<li><p><a class="reference external" href="http://tracker.ceph.com/projects/ceph-releases/wiki">稳定版和移植小组</a>负责发布<code class="docutils literal notranslate"><span class="pre">小版本</span></code>，其中包含已经移植到稳定版的修正补丁。</p></li>
</ul>

<section id="id7">
<h2>稳定版的生命周期<a class="headerlink" href="#id7" title="Permalink to this heading"></a></h2>
<p>一个稳定版系列的生命周期大概是首次发布月份之后的 24 个月
（也就是两个 12 月的发布周期）。比如，
Mimic (13.2.z) 会在 Octopus (15.2.0) 发布后不久走进生命尾声（ end of life, EOL ）。
一个版本的生命周期可能会差别很大，它取决于稳定版发布的速度。</p>
<p>关于所有版本的详细信息，以前的和现在的，都可以在 <a class="reference internal" href="../#ceph-releases-index"><span class="std std-ref">Ceph 版本（索引）</span></a> 找到。</p>
